PR and FP,

"I think you are bumping in the wrong direction

To simplify thinking about this, I am going to ignore any oleo compression effects and imagine that the wheel is rigidly fixed to the airframe by the gear leg.

Then if one wheel is raised by 0.3048 m due to a bump, then the wing rib directly above the wheel is also raised by the same amount. It is completely independent of where the gear leg is attached. If referring to a wing rib, it is completely independent. However, it depends on where the rib is relative to the wing, or aeroplane."

--------------------

Raising a rib that is twelve feet from the centre line a foot is going to affect the whole aircraft less than a rib that's only six feet away.

Numbers made up, I haven't a clue what the difference in mounting points is.
